TURNSTILE Filed Dec. 21. 1928 3 Sheets-Sheet 3 [NVENT 1 Patented July28, 1931 I HERBERT BARcRorronnnnydr TORONTO, oNTARIo; CANAD Applicationfiledpecember 21, 1928. Serial no. 327,551. r

My invention relatesto improvements in turnstiles, and oneob ect of mylnvent'ron 1s to provide a turnstile which, while it may be usedintheordinary way to control trafllc through, a given passage, and also torecord the volume oftraffic, if desired, passing therethrough, may beZtdJ-LlStGCl' so as to oiler the minimum of resistance to streams oftraiiic down each side thereof without requiring'the operation of theturnstile, in contrast totheimpedance of traiiic by turnstiles as nowmanufactured, in that the common type of turnstile must rotate at alltimes when traffic passes through the passage in 1 which theturnstile islocated, andthe result is that traffic cannot pass down each side ofthis standardtype 10f turnstile injthe same direction, asis possiblewith thesubject-mat tnthepresent application; therefore by 1 means ofthejsaidjinvention any given body.

of people. can pass down each side of this tnrnstile ina commond1rect1on,-'tor example,

and so vacate anygiven building or area at much less time than ispossible with theold style of turnstile. The foregoing feature is a1veryimportant one, also in the caseof fire. Another object of myinvention is to provide means to permit certain of the arms ot theturnstile to bemoved independent of the recording action of theturnstile to lie in a position substantially parallel to the passage inwhich the turnstile is located, in

broughtto rest by the operator, thus avoiding breakage. A still furtherobject of the invention is to provide means to prevent the backwardturning of the turnstile and thusavoid deranging the indicator when sameis used with this gtur-nstile; A still further object of my invention inits most specific embodiment is to pivota'lly mount the arms of theturnstilein ahead rotatably carried by a base or column, and to providemeans to permit opposingpairs of arms" to be moved independently ottheother pair of arms, while at the same'time this other pair of arms arelocked in position, and in the following specification and the drawingsforming part thereof, I shall describe and illustrate one embodimentwithin my invention, and whatlf claim as new will be set. forth in theclaims. forming part of this specification. 1

Fig. 1 is an elevation. of a turnstile embodying my invention, showingthe. parts thereof in position to control the passage'of traflic, andFig.2 is a plan of my turnstile showing certain of the" arms moved I inparallel relationship to the fixed arms to permit traffic topa'ss in thesame or opposite directions down each side'of the turnstile. Fig. 3 is avertical central section on the 1ine8-3, Fig.'1, on an enlarged scale.Fig.

4 is in part,a vertical central" section through 1 the head of theturnstile, showing the positions of the upper and lower locking sleeveswhen it is desired to move'the' pairs of arms lying substantially atright angles to the direction of trafiic through a passage so that theymay occupy the positions shown in Fig. 2. Figs. 5 and Gare horizontalcross sections on the lines 55, and 6-6, respectively, Fig. 3. Fig. 7 isa horizontal cross section on the line 7,7, Fig. 4. Fig. 8' is ahorizontal cross section on the line 8-8,' Fig. 3. Fig. 9is a plan ofthe upper locking sleeve, and Fig.10isa planof the underside of a lowerhead block.

In the drawings, like characters of reference refer to the same parts.

In common with other types of turnstiles, I use a tubular base or column2 which maybe secured in place after any suitable man ner. Locatedaxially within the base or column 2 is a post 3 which extends above saldbase or column. This post 3 i s centrally 2. The said bridge pieces arecentrally bored axially with the base or column 2' to;

receivethepost 3, and any suitablemeans such as a pin 5 may be passedthrough the lower bridge piece and 1ntothe post 3 to removably hold itin position;

The head of the turnstile is composed-of the following, elements: 6 is acentrallyapertured upper head block, and 71. is acentrally-aperturedlower head block. As shown in Fig. 3 these head blocks are mounted onthe post 3, and are coupled together in spaced relation by a sleeve 8.The ends of this sleeve are. secured to the re.- duced inner portions ofthe saidblocksby anyv suitable means, such as screws 7 9 (Fig.4). v a

The said head blocks are very similar in construction, and each isprovided with pairs of aligned holes which lie parallel to thelongitudinal axis of the turnstile, and are located substantially at 90apart. Obviously said holes in the upper head block 6 are in. alignmentwith the said holes" in the lower head block 7 and positioned in theseholes are rods 10. The lowerends or" the rods 10 are supported in thebottom of the holes receiving same asshown in, Fig.

The said head blocks are provided with spaced lugs 11 through which thesaid pairs of holes in the said head blocks pass and in which the rods.10 are located, and posi-,

tioned between each pair of lugs 11 are the inner ends 12 of thehorizontal members .13 ot-the arms'of the turnstile. The upper and lowersurfaces of these inner ends 12 are substantially parallel, and theyoperate, in contact with their respective sides ofthe said lugs.- Asshown clearly in Figs. 3 and 6, the rodsv 10 pass through the said innerends "12 thereby pivoting the arms of the turnstile to salthlleilld;

It will be, understood that'the space separating thesaid lugs llforms anannular channel in each of the said head blocks of suflicient size topermit freedom of movement of said arms. a plate centrally aperturedthrough which the post3 passes, andthis plate is supported by the baseor column 2 and is constructed to interfit therewith in any suitablemanner so as to be stationary. The preferred construction to hold theplate 14 in fixed relation to the base or column 2 is the provision ofdependent lugs 15 which are received by correspondingly-shaped slots 16formedin theupper end of the b'aseor column 2.. For ease of assembly,theplate 14 is made separate to the base or column 2 though it is withinthe scope of my invention to form Figs.v 3 and 4.

this plate 14 integrally with said base or column. s

Hand 18 are upper and lower locking sleeves substantially identical inconstruc tion, though one is larger than the other. Each locking sleeveembraces an inwardlyextending tubular member 19; a horizontal flange 20,and a vertical flange 21. Each vertical flange is provided with openings22 whichopenings are located to be in alignment with the horizontalmembers 13 of the arms. .Each locking sleeve'is also provided with aplurality of pierced lugs 23 through which the rods 10 pass, as shownclearly in The tubular member 19 of each locking sleeve is exteriorlythreaded to receive an internally-threaded adjusting sleeve 24 (Figs '3.and 4). This adjusting sleeve 24 while free to-be turned around thevertical axis of thesaidhead is fixed against movementvertically by anysuitable means. The preferred means embraces centrally-apertured pla'te25 which surrounds the sleeve 8 and is keyed thereto'by any suitablemeans such asa screw 26. his plate 25 is also provided with a pluralityofholesto permit the rods'lO to pass therethrough, and in its perimeteris formed a groove 27 in which is located a ring 28 made of two segmentsso as to be placed in position. Each segment of this ring is suitablysecuredto the'adjusting sleeve 24 by means of screws 29, and ofcourse'is located on the inner side of said sleeve'and substantiallymidway the:

height thereof. By turning the sleeve 24 the upper andlower lockingsleeves 17 t and 18 are moved towards each other out of engagement withand above respectively, the horizontal 'members 13(Fig. 4) thuspermitting of the movement of certain'pa'irs of arm'sof the saidturnstile into the position shown in Fig. 2, forthe purpose alreadymentioned. By reversing the movement of the said adjusting sleeve, thesaid to normal locking sleeves are moved back of course position: this.return movement cannot be given these sleeves until the arms of theturnstile occupy the positions shown in Fig.1. V

30 is a cap plate which is keyed to the upper end of the post 3 by meansof a pin of the upper head block 6' to which it is secured by anysuitable means such as the screws 33. This flanged plate forms part of aregister, but as the same does not to in part of myiinvention, I do notfind it necessary to further illustrate it. Various types ofregistersfor the purpose in question are in use. This register isprovided with a register;

cover 34' suitablyseeurecl in; lace to thecap plate" 30, and this coverhas a slot' to! per m'it the register to be" seen. As befOre-Inentio'ned,,I do not confine myself to usinga Suitable clutch meansg ofcourse must he p of the turnstile backwards, as when I areg1ster: is'u'ed' this backward movementwould interfere With the correctrejcording oftrai' The type of clutch 1 illustrate for this purpose is well-known;and? it embraces the plate 14' v'vhich is, providedfvvith a'fiange 36"which is provided on:v its inner side' with a ratchet 3 7. plate 14 islocated within the fiang'ecl' plate 1'4 and it isrp'rovided with studs38 located substantially at 180 apart, and on each of these studs'ismounted a pawl 391 tjailj 40 of reach pawl normally rests" inslots-41';formed in opposite" sides of the a boss 42'whieh forms part ofthe'lowerhead block 7 andfprojects below the, 'same;fAs". sh-own clearlyiin '3and 51the post 3 passes 'll'lll'Ollgll saidbboss' and through the plate.14. Whe'nthe' partsarerin the posi tions shown in Figs. 1 and 3,sui'fic1eno' movement ofthe' arms of thetu'rnstile backvvardvvillicause theheadof the turnstileto turn sufficiently to cause-the boss 42' to-move thepawls 39 into contact with the ratchet 37 and prevent furtherbacltwardmovement,

as shown in 5; Movement given to: the headof the turnstile ifn' aproperdirection will causeithe'hoss 42tomove the'pawls' 39 out" of contactwith the ratchet "37, the re leasing movement of said pawls' being limQited by thestudscarried bythe plate 145). Embraced in the s'aidheadofi'the turn-- stile are four pins located suhstantiallyj pin ismounted ina .pocl tet 46formed in the central portion of the"'loWer headblock and the axis of each of these pockets is in alignment with thelongitudinal axis of the lower horizontal members 13 of each" arm of theturnstil e; These pocliets open into the annular space separating thelugs 11' of said lower headblock. Formed: in opposite sides'of'the' post3 are" two pockets lfi, and

these pockets are in alignment with" any given pairgof pockets 4:5 Uponreferring:

particularly toFig'. 6; it" will" be noticed tliat the line 47 re)resentsaradiusgreaterthan theline 48. I hereforiif the horizontal pins414 in Fig 6 bein alignment With the pockets 4 6, obviously if themembers 13' shown'fin horizontal position Fig; 6' be moved in? thedirections indicatedby arrows, the lower cornersl of these horizontalmembers by reason of their greaterradiu's will forcethe i horizontalpins 44' inwardly'intothe'pockets 46 to. permit the clearance of saidcorners With saidv p ns so that the pairs of arms under consideration mbe moved into the position shown in 2; By reason of the to preventsubstantial movement fact there are" only two pockets the pins 44 shownin verticalf 'positionjin Fig. 6; will he incontact with the imperforatesurfacesof. the post 3, and consequentlythe'horizontal members 13shown'in' vertical positionin Fig. '6' becauseof the greater radius oftheir corners cannot have movement by their associated pins 44*, and

consequently the horizontal normally-posh through an angle of 90topermit one pers son to-pass, and When; this person has passed it isusual to employ means to prevent the passage ofanother person until hisfare has been paid;v The-locking means I illustrate is 1 Well-known, andembraces a lbcking' arm' 50 Which is suitably pivoted Within the base orcolumn 2'; The upper end of this locking" arm normaliyoperates'in' aslot 51 which is fornie'd in" projection forming part of the plate 14;In this positionthe locking arm is obviously in the path of movement ofthe lowermost horizontal member of one of the arms; anclfordinarily thishorizontal memher would come in contact with this locking aria, Byreason of the pivotal mountingr l o fthe armsfof my turnstile, Ifind it.advisable" t'oprovide sturdy means forming part J of the lowerhead block7 to recei'vethe blow of't he'head" of the turnstile developed bycontact with thelocking arm 50. This" means comprises four lugs- 52which are substantially at 9Q apart, and they project beyond themainhody of said lower head blocl; as shown clearly in- Fig. 10, and arelocated underneath the normal positions oi" rest of the lower horizontalmembers. When the locking arm 50 is thrown into the path of movement ofany given arm, it Will also be 1n the'path of movement of one of thelugs 52{('F1g. l0), and consequently these lugs in turn will receive theiinpactofthe blow.

There is always a slight movement possible to the arms of my turnstile,and: any blow they may receive by contact with: the arm 50 will be veryslight.

Thelocking arm 50 is coupled by a rod 53 tothe foot trip 54, and bymeans of the spring, couple'cl at its upper end in any suitable Way tothe hase'or coliimn 2', and at its lower'end to'the foot trip 54!, thelock ingarm' 50 is automatically returned to noriso 7 requirements malposition when pressure againstsaid foot trip 1s removed.
